Heavy Duty Socks are ideal foot protection for tough jobs outside in cold weather.

Manufactured from 100% polyamide, these socks are lightweight and soft but are exceedingly hard wearing, with a reinforced heel and flat toe seams. Unlike most other sock brands, this Sub Zero range has a non-elasticated comfort cuff finish achieved by the in-built stretch of the polyamide yarn, keeping your socks pulled up without them cutting in to your calfs. A hydrophilic treatment applied during the dyeing process also helps to manage perspiration as well as decrease drying times.
